We've added a new metric to CrUX Dashboard and Pages reports: Round Trip Time (RTT).

Round Trip Time (RTT) displayed alongside Other Web Vitals.
Round trip time data is newly available to Google's Chrome User Experience Report (CrUX) dataset.
RTT measures the time it takes for a request to travel from browser to server, and back.
Round trip time is a valuable metric to understand latency that customers experience, alongside Time to First Byte.

Mobile traffic for Australia's top retailers, ranked by Round trip time
Using the updated CrUX Dashboard and Pages reports, you can:
- Understand the latency experienced by visitors to your site
- Compare Desktop, Mobile and Tablet round trip time data
- Identify trends in latency over time
At the moment CrUX includes 75th percentile (p75) data for RTT, with histogram data likely available in the future.
